(Cl. Sli-'43) 3 Claims.`

My invention relates to a shaving device of the dry shaving or shearing type and the objects of my invention are:

First, to provide a reciprocating shaving member that is so shaped that it readily cleans itself or may be readily cleaned;

Second, to provide a shaving device of this class in which the shaver member casing is so arranged and slotted that it provides a maximum shaving efficiency;

Third, to provide a shaving device of this class in which a reciprocating shaving member is so shaped and arranged in relation with its casing and shearing member that provides a maximum of shaving efficiency;

Fourth, to provide a shaving device v of this class with novel means of supporting the shaft relativeto the head casing member and the shaving member;

Fifth, to provide a shaving device of this class in which the shaving member provides a slotted cutting surface its complete width, whereby its shaving efficiency is increased;

Sixth, to provide a novel means of supporting the shaver member casing on the casing head;

Seventh, to provide a novel means of supporting the reciprocating shaver member relative to the casing head; and

Eighth, to provide a novel shaving device of this class which is very simple and economical :f

of construction, easy to operate, eicient in its action, and which will not readily deteriorate or get out of order.

With these and other objects in View as will appear hereinafter my invention consists of certain novel features of construction, combination, and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims reference being had to the accompanying drawing and to the characters of reference thereon which form a part of this application in which:

Figure l is a side elevational view looking toward one end of the shaving member and its casing; Fig. 2 is a side elevational view at right angles thereto taken from the line 2-2 of Fig. 1; Figure 3 is a sectional view taken from the line 3--3 of Fig. 2 showing some of the parts and portions in elevation to facilitate the illustration; Fig. 4 is a sectional view tafken from the line 4 4 of Fig. 1 and Fig. 5 is a sectional view taken from the line 5-5 of Fig. 1 showing some of the parts and portions in elevation to facilitate the illustration. l 4 Similar characters of reference refer to s1mllar parts and portions throughout the several views of the drawing:

The handle member l, shaft 2, head casing member 3, ball bearing 4, shaver member casing 5, shaver member 6, screw 1, pins 8, and screws 9 constitute the principal parts and portions of my shaving device.

The'handle member I is a hollow cylindrical member adapted to be grasped at one end by the hand of the operator and is provided on its head end with a reduced cylindrical portion la. over which is mounted in snug fit the sleeve portion 3a of the head casing member 3 so that its outer surface isush with the outer surface of the handle l at its larger portion as shown best in Figs. 1 and 3 of the drawing. 'I'he sleeve portion Id is provided with an inwardly extending annular ange lb which forms a support between said flange Ib and the end of the sleeve la for the ball bearing 4 which is mounted on the shaft 2, which shaft 2 is revolubly mounted in the handle member l and the head casing member 3. This head casing member 3 is extended in opposed directions merging with the sleeve portion 3a forming an elongated somewhat elliptical form of back member 3b with two spaced forwardly extending portions 3c and 3d shown best in Fig. 4 of the drawing. Secured in this extending portion 3d is a plurality of pins 8 which extend slightly inwardly from the inner side and form a bearing against which one side of the shaver member 6 rests in its reciprocation and forming a bearing for the one side. This shaver member 6 is relatively thick and flat at its inner edge and rests against adjusting screws 6a at its opposite end shown best in Fig. 5 of the drawing providing for the adjustment of this shaving member, and these screws 6a also provide a bearing for said member at its inner edge. This member 6 is also provided with a slot in the middle at 6b shown best in Fig. 5 of the drawing in which an eccentric end 2a of the shaft 2 is adapted to revolve for reciprocating the shaver member 6 with the revolution of the shaft 2.

It will be here noted that the extended end of the eccentric portion 2a of the shaft 2 is engaged by a screw 1 which is set into the casing 3 shown best in Figs. 2 and 3 of the drawing which provides means for adjusting the shaft relative tothe casing 3 as well as providing a journal and support for the shaft at its extreme end, it being noted that this screw 'I is concentric with the main portion of the shaft 2 and eccentric with the axis of the portion 2a.

It will be noted that the shaver member 6 is shaped in curved offset relation at 6c and then turns backwardly at 6d and extends backwardly at substantially right angles .to the back portion of the shaver member and to the opposite side of its axis to provide a relatively broad flat surface which is slotted its full length as shown best in Fig. 5 of the drawing, the slots extending from the point to the portion 6c.

Mounted over this shaver member 6 and se cured to the head casing member 3 is the shaver casing member 5 which is substantially U-shaped in cross section, except that it is provided with a flat outer surface and also a flat inner surface for engagement with the outer side of the portion 6d of the member 6. This flat portion 5a'is ,slotted its full width as shown best in Fig. 5 of the drawing and these slots extend around and extend backwardly some distance to the point 5b shown best in Fig. 3 of the drawing, thus provided a long angular slotted portion in this casing member 5 providing shearing portions engageable with the shearing portions of the member 6. This casing member 5 is secured in rigid relation with the casing member 3 by means of screws 9 which ex tend through one/side of the member 5 into the member 3c so that the inner side of the at portion 5a of the member 5 is in substantial engagement with the outer side of the portion 6d of :the member 6 for providing a relatively broad shearing relation for providing efficiency and ready clean- `claim as new and desire to secure by Letters Patent is:

vl. In a shaving device of the class described, a

reciprocally mounted shaving member provided with a long fiat straight shank portion, a head casing member slotted to receive said shank portion forming two spaced walls, a plurality of pins mounted in one side wall of said slot and extending from one side in engagement with one side of said shank portion, adjusting screws in said head casing member adapted to engage the inwardly extending edge of the shank portion of said shaver member for adjusting the position of said shaving member, an extended oiset curved portion extending from said shank portion, another straight extending portion substantially at right angles to said shank portion, and a shaving member casing provided with a straight flat inner surface against which the straight portion of said shaver member reciprocates provided with slots extending across the face of said member and some distance along the forward side thereof.

2. In a shaving device of the class described, the combination of a reciprocally mounted slotted shaving member provided with a long at straight shank portion, a head casing member slotted to receive said shank portion forming two spaced walls and a plurality of pins mounted in one side wall of said slot and extended from one side with their ends in engagement with one flat side of said straight shank portion.

3. In a shavin-g device of the class described,

kthe combination of a reciprocally mounted slotted shaving member provided with a long :dat straight shank portion, a head casing member slotted to receive said shank portion forming two spaced Walls, a plurality of pins mounted in one side wall of said slot and extended from one side with their ends in engagement with one flat side of said straight shank portion and adjusting screws in said head casing member in the opposite side wall from said pins adapted to engage the inwardly extending edge of the straight shank portion of said shaver member for adjusting the positionbf said shaver member in opposed relation to said pins. 1
